Abstract
Systems and processes for fluid regulation may provide diagnostic information that is useful for evaluating the condition and/or needed repairs/maintenance for fluid regulation systems. In particular implementations, a system and process for fluid regulation may include the ability to receive a representation of an input signal to an electric-to-pressure converter for facilitating positioning of a fluid regulator component, the electric-to-pressure converter adapted to be part of a fluid regulation system including a fluid regulator and a fluid regulator controller, and to determine at least one fluid regulation system condition based on the converter input signal.
Claims23
A method for fluid regulation, the method comprising:
- receiving a representation of an input signal to an electric-to-pressure converter operable to facilitate positioning of a fluid regulator component, the electric-to-pressure converter adapted to be part of a fluid regulation system comprising a fluid regulator and a fluid regulator controller;
- determining at least one fluid regulation system condition based on the converter input signal, wherein determining at least one fluid regulation system comprises determining whether the converter input signal is outside an acceptable range and determining the amount of time that the converter input signal is outside of the acceptable range;
- and
- diagnosing a mechanical condition based on the fluid regulation system condition.

(canceled)
A system for fluid regulation, the system comprising:
- an electric-to-pressure converter operable to receive an input signal for positioning a fluid regulator component and to generate an appropriate pressure in response thereto;
- and
- a processor coupled to the electric-to-pressure converter, the processor operable to:
- receive a representation of the converter input signal;
- determine at least one fluid regulation system condition based on the converter input signal, wherein determining at least one fluid regulation system condition comprises determining whether the converter input signal is outside an acceptable range and determining the amount of time that the converter input signal is outside of the acceptable range;
- and
- diagnose a mechanical condition based on the fluid regulation system.
(canceled)
A system for fluid regulation, the system comprising:
- a fluid regulator comprising a stem;
- a fluid regulator controller coupled to the fluid regulator, the fluid regulator controller comprising:
- an electric-to-pressure converter, the converter operable to receive an input signal for positioning the stem and generate an appropriate pressure in response thereto, and
- a processor coupled to the electric-to-pressure converter;
- a position sensor for sensing a position of the stem;
- a temperature sensor for sensing the temperature of the fluid regulation system environment;
- and
- a pressure sensor operable to sense the output pressure of the electric-to-pressure converter;
- wherein the processor is operable to:
- receive a representation of the converter input signal, the stem position, the environment temperature, and the converter output pressure;
- determine a least one fluid regulation system condition based on the converter input signal and or more of the stem position, the environment temperature, and the converter output pressure, wherein determining at least one fluid regulation system condition comprises determining whether the converter input signal is outside an acceptable range and determining the amount of time the converter input signal is outside an acceptable range;
- and
- diagnose a mechanical condition based on whether fluid regulation system condition.
